2. Challenging issues Meso-level (topic and domain delineation) Optimizing combination of focused IR, typically bottom-up, and mapping, especially for delineating topics and domains Find optimal combinations of multi-network approaches combining/comparing Citations Texts (lexical and semantic approaches) Authors/ communities Taking the best of each world data-mining mix and/or " sociologically-correct" juxtapositions trade-off technical efficiency, easy interpretation of processes and maps, expressive power of metaphors e.g. geographic
